The DHQ is a long and detailed questionnaire and is probably as good as any we could have chosen. People deal with stress differently, and the person’s assessment of their own feelings of stress may be more important. The details of the correlations are presented in Table 2 and Figures 1, 2, 3, 4, 5, and 6. It has also been suggested that since the eight questions used by Spencer et al. Validity Convergent/Concurrent. Convergent validity occurs where measures of constructs that are expected to correlate do so. Divergent Validity – When two opposite questions reveal opposite results. Convergence of independent methods: the distinction between reliability and validity. In this current study, validity was assessed by determining the correlation coefficients between the component raw scores on the SLIQ and the appropriate referencestandards(DHQ,SRRS,Question1ontheSF36, andstepperdayonthepedometer).ANOVAwasconducted Sorry if this isn't the right place to post this but I can't think of any other subreddit . , Concurrent validity is one of the two types of criterion-related validity. E.G. [19]. Initial psychometric testing of the SLIQ [10] resulted in a test-retest reliability between 0.63 and 0.97; a Cronbach α of 0.58 for diet and 0.6 for physical activity, and blinded external validity of 0.77.

As mentioned in the results, the correlation for SLIQ stress score versus the SRRS stress score is negative. In convergent validity, we examine the degree to which the operationalization is similar to (converges on) other operationalizations that it theoretically should be similar to. One reason is that Spencer included BMI which is not a lifestyle but rather a consequence of lifestyle; moreover, there have been no psychometrics conducted on the eight questions unlike the SLIQ which has a developing literature. Criterion validity (concurrent and predictive validity) There are many occasions when you might choose to use a well-established measurement procedure (e.g., a 42-item survey on depression) as the basis to create a new measurement procedure (e.g., a 19-item survey on depression) to measure the construct you are interested in (e.g., depression, sleep quality, employee commitment, etc. Concurrent validity is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes. Convergent validity refers to the observation of strong correlations between two tests that are assumed to measure the same construct. Validity correlation coefficients for diet, physical activity, and alcohol consumption are sufficiently strong to make the SLIQ useful in research and clinical settings. This is despite use of the most conservative estimate—the lower bound of the 95% confidence interval for the Pearson Coefficient. If the scores for each employee on both tests are closely related, then the new scale is said to have high concurrent validity. Concurrent validity refers to whether a test’s scores actually evaluate the test’s questions. Concurrent vs. Predictive Validity. Limitations. The additional variation in 6MWT explained by the DGI when added to a model with the BBS was 7.78% (95% CI: 0.6%, 15%). Concurrent validity is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes. Criterion validity (concurrent and predictive validity) There are many occasions when you might choose to use a well-established measurement procedure (e.g., a 42-item survey on depression) as the basis to create a new measurement procedure (e.g., a 19-item survey on depression) to measure the construct you are interested in (e.g., depression, sleep quality, employee commitment, etc. Both reliability and validity concepts require that agreement be-tween measures be demonstrated. The SF36 is a health status measurement tool used in over 4000 published studies worldwide. The mean age was 65 years (SD = 14.5 years) with a range 40–95 years; nearly sixty-six percent were females. It is based on the assumption that different measures of the same hypothetical construct ought to correlate highly with one another if the measures are valid. Finally, we compare the overall SLIQ score with the score on the eight-question risk assessment developed by Spencer et al. Convergent and concurrent validity of a report- versus performance-based evaluation of everyday functioning in the diagnosis of cognitive disorders in a geriatric population - Volume 30 Issue 12 - Elise Cornelis, Ellen Gorus, Karen Van Weverbergh, Ingo Beyer, Patricia De Vriendt [19]. However, the SLIQ measures the person’s assessment of their current stress level while the SRRS simply scores stress events in a person’s life over the previous year. CONVERGENT, DISCRIMINANT, CONCURRENT VALIDITY AND SF-6D was calculated with and without the weights which rep- RELIABILITY OF THE EQ-5D(CHILD): RESULTS resent the preferences of population about different health status. If the scores for each employee on both tests are closely related, then the new scale is said to have high concurrent validity." Convergent validity is one of the topics related to construct validity (Gregory, 2007). . Convergent Validity – When two similar questions reveal the same result. A French version is also available, but none of the psychometric testing has been carried out in French. Divergent Validity – When two opposite questions reveal opposite results. As far as I could see they both increase the validity of research by showing that related variables or constructs are related to their research. ex. We believe the SLIQ is sufficiently valid when compared to reference standards to be useful as a brief assessment of an individual’s cardiovascular lifestyle in research and clinical settings. Showing that an IQ test is valid by comparing the results of it to academic results and seeing a positive correlation. In reality, even measured variables that are designed to measure different conceptual variables will often . One hundred and ninety-three adults completed all the questionnaires allowing correlational statistics to be completed. Ideally, this means testing the subjects at exactly the same moment, but some approximation is acceptable. The concurrent validities between the test and other measures of the same domain are correlational measures of convergent validity. Convergent validity and discriminant validity are never all-or-nothing constructs, and thus it is never possible to defi nitively “prove” the construct validity of a measured variable. The correlation coefficient, usually designated as “ Could you possibly explain here what's making it difficult for you to differentiate the two from one another? Also, as anticipated, the LEAS-C was more strongly associated with emotion comprehension than emotion expression (Bajgar et al., 2005). Similarly, in a health research setting the issue of participant burden has to be considered and long detailed questionnaires should be avoided. The higher the score the higher the likelihood of experiencing stress [13, 14]. , Testing for this type of validity requires that you essentially ask your sample similar questions that are designed to provide you with expected answers. Another way of measuring convergent validity is to look at the differences in test scores between groups of people who would be expected to score differently on the test. Each component is assigned a category score of 0, 1, or 2, based on raw scoring of questions related to each component. They give employees the scale to fill out on the same day as a similar, but longer and decades-old leadership test. ), SLIQ versus alcohol consumption ( A subreddit for questions about the mind and behavior. Pearson’s correlation coefficients of concurrent and convergent validity. ANOVA was conducted to determine if the three categories, unhealthy, intermediate, and healthy, were separately distinguishable populations for each component and for the overall SLIQ score. This re-quirement is evidence of convergent validity. This is similar to concurrent validity (which looks for correlation with other tests). Press J to jump to the feed. This research was reviewed and approved by the Human Investigation Committee of Memorial University of Newfoundland, Canada. Subsequently two further blocks of 100 people per age group were contacted until we had sufficient sample size. In the figure below, we see four measures (each is an item on a scale) that all purport to reflect the construct of self esteem. Convergent validity video that explains the definition in a dynamic and interactive way. Like to me the examples given just seem so similar, I have no clue how to differentiate them because in both examples they're comparing scores between two tests. It measures five lifestyle risk factors and provides a score for each component, as well as an overall lifestyle score. Measuring human behaviour is not an exact science and rarely can it be done with the precision found in fields such as engineering. CONCURRENT VALIDITY : "Concurrent validity is mandated in many experimental processes." [, Self-assessed health on the SF36 (Question  1), S. S. Bassuk and J. E.

Others divide the correlation coefficient into three categories where an Finally, the study population was somewhat skewed towards women (65%) and older age group (mean age 65 years). Therefore, our sample size of 193 provided sufficient power since all our correlations turned out to be greater than 0.2. Analysis. Concurrent validity is determined by comparing the score on the instrument of interest; in this case the SLIQ, with the score on a reference standard—a measurement tool that is known to accurately measure that same construct. While lifestyle and health status are related, they would not be expected to have high correlation since a change in one may precede or follow the other rather than necessarily exist concurrently. For example, let’s say employers have designed their own scale to assess the leadership skills of their employees. Convergent validity is a subcategory of construct validity. One is to correlate the scores between two assessment tools or tools’ sub-domains that are considered to measure the same construct. The practices have electronic medical records (EMRs). Some other types of validity are: Composite, Concurrent, Convergent, Consequential, Curricular and Instructional, Ecological, External, Face, Formative validity & Summative Validity, Incremental Validity, Internal, Predictive, Sampling, and Statistical Conclusion Validity. ); there is also good correlation between the SLIQ physical activity component and the number of steps over three days as measured by a pedometer ( ), and SLIQ versus Question 1 on SF36 ( I’ve never heard of “translation” validity before, but I needed a good name to summarize what both face and content validity are getting at, and that one seemed sensible. Validity Convergent/Concurrent. , share. Convergent validity video that explains the definition in a dynamic and interactive way. Initially 100 people in each group were contacted by letter. Criterion validity evaluates how closely the results of your test correspond to the … The SRRS collects information on stressful life events in the past year. the degree of communication between two measurements at the same time, primarily the investigation of one exam's validity by comparing its outcomes with another correlated exam at the same time. In this case, we used the responses to the first question on the SF36 which is a self-assessment of one’s health status.

Convergent validity is a subcategory of construct validity. include concurrent validity, construct validity, content validity, convergent validity, criterion validity, discriminant validity, divergent validity, face validity, and predictive validity. However, whilst concurrent validity compared a new measurement procedure with a well-established measurement procedure, both measurement procedures are new when testing for convergent validity. Is there anyone that could explain it and provide some examples?? Lifestyle issues including physical activity, diet, smoking, alcohol consumption, and self-reported stress have all been shown to predispose people to higher risk of cardiovascular disease. Convergent validity states that tests having the same or similar constructs should be highly correlated. Convergent validity is measured by comparing the instrument in question with another instrument that measures a related, but different, construct. The letters briefly explained the study and provided the phone number of the research assistant to be contacted if they were interested in taking part. Concurrent validity focuses on the extent to which scores on a new measure are related to scores from a criterion measure administered at the same time, whereas predictive validity uses the scores from the new measure to predict performance on a criterion measure administered at a later time. In psychometrics Concurrent validity is demonstrated when a test correlates well with a measure that has previously been validated. Psychometric properties of this scale have not been reported. values in the moderate-to-strong categories. 2.5. It is a parameter used in sociology, psychology, and other psychometric or behavioral sciences. eaten on a weekly basis over the previous year. Testing for this type of validity requires that you essentially ask your sample similar questions that are designed to provide you with expected answers. As evidence of convergent/ concurrent validity, Buss and Perry (1992) reported positive correlations between the BPAQ subscales and various trait measures as follows: BPAQ Physical Aggression correlated .20 (men) with Activity, .28 with Impulsiveness, .28 with Assertiveness, and .36 with Competitiveness. Some investigators believe a correlation between 0.0 and 0.25 represents a weak relationship, 0.26–0.50 a moderate relationship, 0.51–0.75 a strong relationship, and greater than 0.75 a very strong correlation. published a study completed in Australia on healthy elderly men. The correlation coefficients reported in this study vary from 0.264 to 0.679. as a level of strong correlation. The scoring template is shown in SupplementaryFigure2. In contrast to concurrent validity, convergent validity was consistently high across all comparisons in this study excluding WHR as measured by LS2D and Gulick tape. This video covers material from Research Methods for the Behavioral Sciences (4th edition) by Gravetter and Forzano. Validität (lateinisch validus „kräftig“ „wirksam“; englisch validity; auch: Gültigkeit) ist (neben der Reliabilität und der Objektivität) ein Gütekriterium für Modelle, Mess-oder Testverfahren.. Validität bezeichnet in der Empirie die inhaltliche Übereinstimmung einer empirischen Messung mit einem logischen Messkonzept. It also collects detailed information on alcohol consumption [11, 12]. This paper reports on the concurrent validity of the physical activity, diet, alcohol, and stress components of the SLIQ. The SRRS takes an interesting approach to assessing stress in a person’s life but one could argue there are more modern approaches, and perhaps we should have chosen one of those. This study provides further psychometrics on the Simple Lifestyle Indicator Questionnaire (SLIQ), a short, easy-to-use instrument which measures all these lifestyle characteristics as a single construct. Both convergent and concurrent validity are ways of assessing construct validity by examining the strength of the relationship between the scores from two different measurement procedures. Convergent Validity – When two similar questions reveal the same result. Convergent validity is assessed by calculating AVEs, i.e., Average Variance Extracted for each construct and should be > .50. Contrasted groups. Categorically, a person is considered “unhealthy” if they have a SLIQ score of between 0 and 4, “intermediate” if the SLIQ score is between 5 and 7, and “healthy” if they score between 8 and 10 on the SLIQ. Convergent validity tests that constructs that are expected to be related are, in fact, related. For example, if scores on a specific form a aggressiveness test are similar to people's scores on other aggressiveness tests, then convergent validity is high (there is a positively correlation between the scores from similar tests of aggressiveness).". Concurrent validity differs from convergent validity in that it focuses on the power of the focal test to predict outcomes on another test or some outcome variable. ), SLIQ versus pedometer ( Concurrent validity in this study is determined for physical activity by comparing the physical activity score on the SLIQ with the steps on a pedometer; it is determined for diet by comparing the raw diet score on the SLIQ with the diet score on the DHQ; it is determined for alcohol by comparing the raw alcohol component on the SLIQ with the alcohol score on the DHQ; and it is determined for stress by comparing the raw stress score on the SLIQ with the stress score on the SRRS. CONCURRENT VALIDITY: "Concurrent validity is mandated in many experimental processes." They compared the response to eight questions on diet, activity, smoking, alcohol, and BMI to a person’s likelihood of dying. New comments cannot be posted and votes cannot be cast, More posts from the askpsychology community. One hundred and ninety-three individuals from St. John’s, Newfoundland, and Labrador, Canada completed the SLIQ and r… Comparison of SLIQ scores in the three category levels of unhealthy, intermediate, and healthy using ANOVA. If it doesn’t show any signs of this validity, it may be measuring something else. Convergent validity, a parameter often used in sociology, psychology, and other behavioral sciences, refers to the degree to which two measures of constructs that theoretically should be related, are in fact related. The SLIQ stress component did not correlate as well as we had hoped with stress as measured by the stressful life events count on the SRRS In 2005, Spencer et al. We will compare the SLIQ lifestyle score to the score on this eight-question scale [19]. It typically is estimated by correlating scores on a new measure with scores from an accepted criterion measure. The only Convergent/ Concurrent validity findings available for the ILP must be derived from regression analyses conducted by Pulford and Sohal (2006). Another way of measuring convergent validity is to look at the differences in test scores between groups of people who would be expected to score differently on the test. I'm studying for a psych research final right now, and I've been trying to understand and differentiate Concurrent Validity and Convergent Validity! In the case of discriminant validity, you could show that there is no correlation at all. Details of education, marital status, income, and BMI are shown in Table 1. , Convergent/Concurrent. Lifestyle issues including physical activity, diet, smoking, alcohol consumption, and self-reported stress have all been shown to predispose people to higher risk of cardiovascular disease. , The concurrent validities between the test and other measures of the same domain are correlational measures of convergent validity. save. Convergent validity is measured by comparing the instrument in question with another instrument that measures a related, but different, construct. Both types of validity are a requirement for excellent construct validity. It is a validated instrument which scores 43 life events from 12 to 100. I know that convergent validity is a type of construct validity, and concurrent is a type of criterion validity, but I'm not sure of the exact difference. We expected a correlation coefficient in the range of 0.2 to 0.4. We also report on convergent validity of the whole instrument and compare the overall SLIQ scores to scores on a similar series of questions that have been correlated with cardiovascular morbidity and morbidity. To establish convergent validity, you need to show that measures that should be related are in reality related. Randomly generated lists of patients in three age groups, 40–59 years, 60–79 years, and 80+ years, were compiled by the clinic staff. . Convergent validity is usually accomplished by demonstrating a correlation between the two measures, although it’s rare that any two measures will be perfectly convergent. The SLIQ is sufficiently valid when compared to reference standards to be useful as a brief assessment of an individual’s cardiovascular lifestyle in research and clinical settings. If the item loads high (preferably > .5) on its parent factor WITH low cross loading (< .32) on the other, then you can assume convergent validity. There are two forms of criterion-related validity: predictive validity and concurrent validity. The data in Table 3 shows that the three categories are clearly separated with almost no overlap. To demonstrate convergent validity, the authors also developed a communal overclaiming measure based on the technique previously developed to measure agentic self-enhancement (Paulhus, Harms, Bruce, & Lysy, 2003). This was the motive behind the development of the SLIQ. intelligence) is actually measuring that construct. In quantitative research, you have to consider the reliability and validity of your methods and measurements.. Validity tells you how accurately a method measures something. None of the differences in convergent and concurrent validity between the BBS and DGI were significant. The SLIQ has 12 questions; three on diet, three on physical activity, three on alcohol consumption, two on smoking, and one on stress—see Supplementary Figure 1 (see Supplementary Materials available online at http://dx.doi.org/10.5402/2013/529645). Convergent Validity. Convergent validity tests that constructs that are expected to be related are, in fact, related. An Moreover, each participant wore a pedometer for three days and returned the pedometer to the research assistant. Published on September 6, 2019 by Fiona Middleton. On the bottom part of the figure (Observation) w… external validity of 0.77. Lifestyle issues including physical activity [1, 2], diet [3–5], smoking [6], alcohol consumption [7], and self-reported stress [8] have all been shown to predispose people to higher risk of cardiovascular disease [9]. Criterion-related validity is concerned with the relationship between individuals’ performance on two measures tapping the same construct. 2013, Article ID 529645, 6 pages, 2013. https://doi.org/10.5402/2013/529645, 1Primary Healthcare Research Unit, Discipline of Family Medicine, Memorial University of Newfoundland, St. John’s, NL, Canada. Criterion validity A measurement technique has criterion validity if its results are closely related to those given by If they don’t, the questions might not be valid. Construct validity means that a test designed to measure a particular construct (i.e. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The pedometer used, the Sportline SL330, has been shown to be equivalent to a reference pedometer which measures within 3% of the actual number of steps [21]. I'm studying for a psych research final right now, and I've been trying to understand and differentiate Concurrent Validity and Convergent Validity! and 0.665, resp. In this current study, validity was assessed by determining the correlation coefficients between the component raw scores on the SLIQ and the appropriate reference standards (DHQ, SRRS, Question 1 on the SF36, and step per day on the pedometer). The two measures may be for the same construct, or for different, but presumably related, constructs. The categorization of individuals as unhealthy/intermediate/healthy was assessed to determine if these three groups were from separate populations; that is, whether the mean and standard deviations of the SLIQ scores in these three groups were separated such that there was very little overlap. Convergent Validity. Concurrent Validity vs Convergent Validity. Convergent validity takes two measures that are supposed to be measuring the same construct and shows that they are related. Criterion validity. And finally Cohen [24] uses a benchmark of Physical activity score was compared with number of steps on a pedometer. This is expected … all SLIQ components are scored such that a higher number means a better lifestyle (in this case lower stress). have been shown to predict mortality, why not we use them rather than the SLIQ for assessing lifestyle. of 1 means a perfect linear relationship. between 0.0 and 0.3 indicates a weak relationship, 0.3 to 0.7 indicates a moderate relationship, and >7 indicates a strong relationship [22]. It was developed as a short and simple health measurement scale [10]. Discriminant validity occurs where constructs that are expected not to relate do not, such that it is possible to discriminate between these constructs. Scatter plots with best-fit lines are also presented for each component. Sign up here as a reviewer to help fast-track new submissions.
